Why Pursue an Online PMHNP Post-Master’s Certificate?

Mental health and physical health are strongly connected — one can affect the other — yet nearly half of all Americans lack access to proper mental health care.* As a nurse practitioner, you’ve seen that poor mental health or mental illness can contribute to chronic health conditions and affect a patient’s well-being. 

According to the American Association of Nurse Practitioners, only 4.7% of the practicing 355,000 licensed NPs in the U.S. are certified in psychiatric/mental health. The need for more PMHNPs is critical.

Marymount’s online PMHNP PMC certificate program provides a pathway for you to fill the need. Our part-time program offers you the flexibility to balance work and education and get certified to treat mental health concerns in patients of all ages.
